Hi, All: Glad to announce that I've optimized StarTracker for iPhone 4S and now it's online. Thanks for the powerful A5 chip, it's running at 60fps even after I add lots of graphics improvements. (it's slow on iPhone4, so this app is 4S only) Now download it from the app store and try out how powerful the iPhone 4S is!! App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
